Subject: [PATCH v2 0/8] scsi: ufs: some cleanups and make the delay for host enabling customizable

Hi,

This patchset applies some driver cleanups and performance improvement
in ufs host drivers by making the delay for host enabling customizable
according to vendors' requirements.

v1 -> v2
	- Add patch #1 "scsi: ufs: fix uninitialized tx_lanes in ufshcd_disable_tx_lcc"
	- Remove struct ufs_init_prefetch in patch #2 "scsi: ufs: remove init_prefetch_data in struct ufs_hba"
	- Introduce common delay function in patch #4
	- Replace all delay places by common delay function in ufs-mediatek in patch #5
	- Use common delay function instead for host enabling delay in patch #6
	- Add patch #7 "scsi: ufs: make HCE polling more compact to improve initializatoin latency"
	- In patch #8, customize the delay in ufs_mtk_hce_enable_notify callback instead of ufs_mtk_init (Avri)

Stanley Chu (8):
  scsi: ufs: fix uninitialized tx_lanes in ufshcd_disable_tx_lcc()
  scsi: ufs: remove init_prefetch_data in struct ufs_hba
  scsi: ufs: use an enum for host capabilities
  scsi: ufs: introduce common delay function
  scsi: ufs-mediatek: replace all delay places by common delay function
  scsi: ufs: allow customized delay for host enabling
  scsi: ufs: make HCE polling more compact to improve initializatoin
    latency
  scsi: ufs-mediatek: customize the delay for host enabling
